Growing up in today’s world means navigating a reality deeply intertwined with social media. For many young people aged 15 to 24, this technology defines their daily experiences.

Adolescents and emerging adults within this age group face unique developmental changes, and their interactions with social media can significantly influence their psychological well-being. Researchers are beginning to uncover how social media feedback, such as “likes,” impacts the developing brain, mood, and behavior.

Adolescence, spanning ages 13 to 20, is a critical stage marked by rapid physical, social, and cognitive growth. Identity exploration and independence become central themes.

Emerging adulthood, encompassing ages 18 to 24, builds on these changes, introducing additional challenges like entering the workforce or pursuing higher education. During these phases, young people experience heightened sensitivity to social feedback, such as peer approval or rejection. This sensitivity is driven by both biological and psychological factors.
